Description
Lake Bomoseen is a freshwater lake in the western part of the U.S. state of Vermont in the towns of Castleton and Hubbardton in Rutland County. It is the largest lake that lies entirely within the state’s boundaries, with a surface area of approximately 2,400 acres (9.6 km2). The lake was formed by glaciation and has an average and maximum depth of 27 feet (8.2 m) and 65 feet (19.8 m), respectively. It drains a 24,770-acre (100.25 km2) watershed, has five major inlets, and empties to the Castleton River, a tributary of the Poultney River, which in turn flows west to East Bay at the southern end of Lake Champlain. Bomoseen State Park occupies a portion of the lake’s western shoreline. Most of the remaining area around the lake is privately owned. The lake has such recreational accommodations as a public beach, marinas, and public boat launches, in addition to the state park. There are approximately 1,000 residences around the lake, as well as restaurants and other commercial facilities.
